Students measure objects in their desks and the data are shown in the line plot below. If the objects are to be connected end to end,what would be the total length?
This question is incomplete because it lacks the diagram of the line plot. Find attached to the answer, the diagram of the scatter plot.
Answer:
35/8 inches or 4 3/8 inches.
Step-by-step explanation:
Reading the line plot, the number of objects is plotted vertically while the length of the object is arranged horizontally on the line plot.
The total length is calculated as: summation of the (Number of objects × Length of the objects)
= [(1/8 ×0) + (1/4×0) + (3/8 × 2) + (1/2 ×3) + (5/8 × 1) + (3/4 × 2) +(7/8 × 0)] inches
=[ 0 + 0 + 3/4 + 3/2 + 5/8 + 3/2 + 0] inches
= 35/8 inches or 4 3/8 inches.
Therefore, the total length of the objects if they are connect end to end is 35/8 inches or 4 3/8 inches.
The surface area of a prism is 224 square inches. What is the surface area of a similar prism that has dimensions that are 1/4 the original dimensions?
Answer:
The surface area of the similar prism is 56 square inches
Step-by-step explanation:
Given surface area of prism, A = 224 square inches
The total surface area of a triangular prism = 2 x Area of triangle + ph
Area of triangle = ¹/₂bh
Where;
b is the base of the prism
h is the height of the prism
p is the perimeter of lateral surfaces
Area of prism involves the product of the dimensions, if the new dimensions is 1/4 the original dimensions;
Product of original dimensions = 224 square inches
1/4 of the product of original dimensions = 1/4 x 224 square inches
= 56 square inches
The surface area of the similar prism = 56 square inches
Thus, the surface area of the similar prism is 56 square inches

Y=78(0.54)^t Identify the initial amount a and the rate of growth r (as a percent) of the exponential function. Evaluate the function when t=5. Round your answer to the nearest tenth.
Answer:
[tex] y = 78(0.54)^t[/tex]
And for this case we want to identify the initial amount and for this case would be 78. And the growth rate can be obtained from the term inside of the parenthesis.
The general model is given by this model:
[tex] y = a (1+r)^t[/tex]
And then [tex] 1+r = 0.54[/tex] and [tex] r = 0.54 -1= -0.46[/tex]
And then we want to find the of the function at t=5 and we got:
[tex] y(5) = 78(0.54)^5 = 3.58 \approx 3.6[/tex]
Step-by-step explanation:
For this case we have the following function given:
[tex] y = 78(0.54)^t[/tex]
And for this case we want to identify the initial amount and for this case would be 78. And the growth rate can be obtained from the term inside of the parenthesis.
The general model is given by this model:
[tex] y = a (1+r)^t[/tex]
And then [tex] 1+r = 0.54[/tex] and [tex] r = 0.54 -1= -0.46[/tex]
And then we want to find the of the function at t=5 and we got:
[tex] y(5) = 78(0.54)^5 = 3.58 \approx 3.6[/tex]
Answer:
Initial amount = 78
Rate of growth = -46%
Y(t=5) = 3.6
Step-by-step explanation:
The general form of an exponential function is:
[tex]Y(t) = Y_0*(1+r)^t[/tex]
The initial value (Y0) is the value of Y(t) when t = 0:
[tex]Y(0) = 78*0.54^0=78[/tex]
Comparing the given function to the general form of the exponential function, the rate of growth 'r' is determined as:
[tex]Y(t) = Y_0*(1+r)^t = 78*(0.54)^t\\78*(1+r)^t = 78*(0.54)^t\\1+r=0.54\\r=-0.46=-46\%[/tex]
At t=5, the value of Y(t) is:
[tex]Y(5)=78(0.54)^5\\Y=3.6[/tex]

How do you find the radius if you know the area of the circle?
Answer:
sqrt(A /pi ) = r
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
Divide each side by pi
A / pi = r^2
Take the square root of each side
sqrt(A /pi ) = sqrt(r^2)
sqrt(A /pi ) = r
Answer:
sqrt(A /pi ) = r

Identify the measure of arc HD◠.
The figure shows a circle and three secants. Points P, K, L, H, D lie on the circle. Secants R L and K H intersect in the interior of the circle. The measure of formed angle is 92 degrees. Secants D R and L R intersect in the exterior of the circle at point R. The measure of angle D R L is 38 degrees. The measure of the intercepted arc that is closest to the angle is 18 degrees. Secant R L intersects the circle at some point. The measure of arc between this point and point K is 102 degrees. Point P lies on secant R D.
The measure of arc HD, which represents the arc between points H and D, is also 102 degrees.
We have,
In the given figure, we have a circle with points P, K, L, H, and D on it. Secant RL and secant KH intersect inside the circle, forming an angle with a measure of 92 degrees.
Secant DR and secant LR intersect outside the circle at point R, forming an angle DRL with a measure of 38 degrees.
The intercepted arc closest to angle DRL has a measure of 18 degrees.
Since secant RL intersects the circle at some point, we can consider the arc between that point and point K.
The measure of this arc is given as 102 degrees.
Therefore,
The measure of arc HD, which represents the arc between points H and D, is also 102 degrees.

The equation of line a is y=-1/4x+3 if line b runs perpendicular theough (2,6) what would be the equation of line b ?
Answer:
The formula of this perpendicular line is y = 4x - 2
Step-by-step explanation:
In y = -1/4x+3 the gradient is -1/4.
If two lines are perpendicular, then their gradients will multiply together to give -1.
Use this to find the gradient a of the perpendicular line.
-1/4 * a = -1
a = -1 * -4 so the gradient a of the perpendicular line = 4.
Substitute (2,6) in y = 4x + b, to find the value of b.
y = 4x + b
(2,6)
6 = (4*2) + b
b = 6 - (8)
b = -2
So now we have our equation.
The formula of this perpendicular line is y = 4x - 2

Find the surface area of the triangular prism. A triangular prism. The base is a right triangle with base 1 foot, height 2 feet and third side 2 point 2 feet. The height of the prism is 3 feet.
Answer:
17.6ft²Step-by-step explanation:
The formula for calculating the surface area of a triangular prism is expressed as shown below:
SA= bh + pH
b= base of the triangle
h- height of the triangle
p= perimeter of the triangle
H= height of the prism
Given b = 1foot
h = 2feet
perimeter of the triangle = sum of all its sides = 1ft + 2ft + 2.2ft
p = 5.2ft
H = 3ft
Substituting the values into the formula for finding the surface area:
SA = 1(2)+5.2(3)
SA = 2+15.6
SA = 17.6ft²
The surface area of the triangular prism is 17.6ft²
Answer:

135 apples are to be packed into boxes.each box can take only 12 apples.find the number of boxes that will be fully packed and the number of boxes that will remain.
Answer:
11 boxes will be fully packed and .25 will be remaining
Our total amount of apples is 135 apples, and the amount that each box can hold is 12.
So, that means we can make an equation for this.
The equation would be 135 = 12x.
Then, to find x we can divide both sides by 12.
135/12 = 11.25
Next, we take 11 and multiply it by 12 to see how many apples it is.
11 x 12 = 132
So, 135-132 equals 3.
3 is 1/4 of 12.
That means 11 boxes will be fully packed and 1/4 of a box will be filled.

A school wishes to use square tiles of artificial turf to cover an outdoor play area that measures 40 feet by 72 feet. Only whole tiles that are congruent squares of the largest possible size will be used. How many such square tiles are needed?
Answer:
45 tiles of dimension 8 ft by 8ft
Step-by-step explanation:
Since the tile is going to be a square, then both sides must be equal.
This means the lenght of the side of the square must divide without remainder, the lenght and the breadth of the outdoor play area. The highest common factor of 40 and 72 is 8. This means that the side of each square should be 8 ft.
This means that 5 of the 8 ft sided tile will cover the 40 ft width of the play area, and 9 of the 8 ft sided tile will cover the lenght of the area.
The total amount of tiles needed will then be 9 x 5 = 45
